To all whom it may concern:

Be it known that we, GEORGE H. Salmon, and SAMUEL F. TAPMAN, J r., citizens of the United States, and residents, respectively, of

Jersey Cit in the State of New Jersey, and

Jamaica,

York, have invented certain new and useful Improvements in Metal Structures, of which the following is -a specification, reference being had to the accompanying drawings,

forming a part hereof.

This invention has been developed primarily with reference to the production of metal poles, such as telegraph poles, etc.,

5 but is applicable to the production of structural elements of metal, and may be regarded as consisting in an improved structural element, whether used for poles or for other purposes. In its most approved form for use as a pole, because the cross section of the element at any point in its length is proportioned-to the load to be borne, the element is tapered in width and-several such tapered elements might be combined and 5 secured together in any convenient manner, as by riveting or spot welding, to form a tapered pole, but whether tapered or not,

each element is preferably formed by shearing in parallel longitudinal lines a plate, such as an angle beam, channel orfiat plate which may be flanged, as a channel plate, while the relatively narrow sheared portions are stretched and displaced to form diagonal truss members. Two or more of such elements may be combined to form a pole or a beam by securing them together at the points of greatest displacement of the sheared members. The invention will be more fully explained hereinafter with reference to the accompanying drawings in which it is illustrated, and in which- Figure 1 is a view in elevation of a pole or ta ered beam formed in accordance with one eature of the invention and viewed from 4.5 9. int at right angles to one of the plates. 'gure 2 1s a similar view of the same a s seen from a point of view at right angles 0 that of Figural.

Figures 3, 4 and 5 are detail views, on a as larger scale, of the structure shown in Figares 1 and 2, Figure 3 being a partial longitudinal section, Figure 4: a partial side elevation and Figure 5 a section on the plane ong Island, in the State of New larger scale, of the construction shown in,

Figures 6 and 7, Figure 8 beinga partial side elevation, Figure 9 being a partial longitudinal section and Figure 10 a'section onv the plane indicated by the broken line 10.10 of Fi re 8. Figure 11 1s a view in side elevation of a quadrilateral structure made up of four elements. I

Figures 12, 13, 14 and 15 are detail views,

on a larger scale, of the structure shown 1n Figure 11, Figure 12 being a partial side elevation, Figure 13 a partial longitudinal section and Figures 14 and 15 being sections on the planes indicated by the broken lines 1414 and 15-15 of Figure 12.

' The improved. structural element is formed of a' plate of metal, of suitable thickness, which, to secure stiflness, may be flanged, like an ordinary channel element or otherwise. In the structure shown in Figures 1-5 the plate a is of uniform width from end to end and is rolled with a solid flat web and flanges a. In the structure shown in Figures 6-10 the plate a is tapered from end to end, so that its cross section at any point will b e proportioned to the load to be carried and unnecessary weight, as at. the upper end of a pole, be avoided. The plate a? may also be flanged at its edges, as at a, as before. In the structure shown in' Figures'1115, each element is of uniform width, as shown in Fi res 1-5, and is made up of a plate a with flanges a.

In each of the structures represented in Figures 1-15 the plate is sheared longitudinally, as at a in parallel lines, a comparatively short distance apart, and the narrow strip a between the sheared lines, is stretched and dis laced as shown, so as to form the diagona s of a truss member. will be noted that by reason of the stretching and displacement of the sheared strips, which remain united integrally at their ends with the body of the late, there is no shortening of the length 0 the element or of the g a manac compounded structure as compared with the original length of the elements, as must be the case in ordinary ex anded metal structures. The number an disposition of the sheared portions (1 will depend in each case upon the use to which the element is to be put. As shown in Figures 1-5 and in Figures 11-44, the sheared I portions are arranged in a single longitudinal series, in a comparatively narrow plate, the length of the sheared portions being varied. In the structure shown in Figures 6-10 the sheared portions are arranged in parallel lines through the wider portion of the plate and in a single line through the narrower porgion, 1the sheared portions being ofuniform 'l lie elements can be used in any desired manner. As shown in Figure 1-15 two of the sheared-elements can be united to form a pole or truss by securing together, as by spot welding, as indicated at a in Figures 3 and 5, the opposed sheared portions of two elements, at the points of greatest displacement. of the sheared and stretched portions; In the construction shown in Figures 1-5, in which the sheared portions, are

rogressively shorter, apole or beam thus ormed will be tapered in one plane, but the weight at any given cross section will be substantially the same.- In the construction shown in Figures 6-10 two elements are united to form a tapered pole, with progressively reduced cross section, by unitin in any convenient manner, as by s ot wel ing, as. at a, the stretched sheare portions tapered by making the sheared portions progressively of reduced length.

Various modes of using the improved elements will sug est themselves and it is to be understood t at, encept as pointed out in the claims, the inventlon is not restricted to any particular combination of elements. i

We claim as our invention: 1 1. A structural metal element consisting of a plate sheared in parallel lines and havat the points of the greatest'displacement.

ing the sheared portions integrally connected at both ends to the plate and stretched and displaced from the plane of the late,

ralit of plate elements, each sheare para lel longitudinal lines and having the 2. A metal structure consisting o a dplum sheared portions integrally connected at both ends to the plate and stretched and displaced from the planes of the plates, the several elements being secured together through the stretched and displaced por' tions.
